Displacement settings in Materials turn material black
Luckily this is a easy one, the only problem was your Displacement node having the wrong values. I downloaded your file and saw that you set the scale on your displacement to something around 47 which is really big, this value controls the overall scale the displacement has meaning a higher value makes the displacement stand out or drop down more.
The middle value called &quot;Midlevel&quot; was set to 5 in your file, but it should be around 0.5 in most cases as it marks the height of the overall displacement (the Midlevel specifically controls what height the colour on your height map right in the middle between black and white would be at, in short its the height of the entire displacement.) Due to it being at 5 in your example, the whole texture got sent up into the air so you couldnt see it anymore, therefore making the object appear invisible because you could only see the orange outline which doesnt go up with the rest of the texture.
Lastly, the displacement texture you're using is almost completely black meaning the texture gets sent down anyways as black indicates a drop in the displacement and white tells it to go up.
I would reccomend you to play around with the displacement node in a test file and learn how the different values work so you can set them up correctly in the future, as well as making your texture artificially brighter so it ideally spans the whole range between black and white, either in a image editing program like Photoshop or using nodes in Blender.
I hope this helps, if it doesn't make sure to comment here again so I can help you further :)
